An insulated wire strung separately or as a twisted pair, used for connecting the two free ends of the circuit of the blasting caps to the blasting unit.

Industry:Mining
An interface between two crystals putting all adjacent ions in an irregular crystalline environment. Compare: lineage
Industry:Mining
An interface that indicates a particular position in a stratigraphic sequence. In practice it is commonly a very thin bed.
Industry:Mining
An intergrowth between two mineral species in which single or multiple unit cells coincide in size and shape, e.g., bastnaesite-synchisite. Compare: distaxy; epitaxy; topotaxy; polycrystal.
Industry:Mining
An intergrowth of a sodic and a potassic feldspar, generally considered to have formed during slow cooling by the unmixing of sodium and potassium ions in an originally homogeneous alkalic feldspar. In an antiperthite, the potassic member (usually orthoclase) forms thin films, lamellae, strings, or irregular veinlets, within the sodic member (usually albite). Compare: perthite
